Abstract: A gas analysis system for analyzing dissolved gas in electrical insulating fluid includes a trap that selectively captures or releases one or more gases, a temperature control device for controlling a temperature of the trap that determining whether the trap is in a gas capture mode or a gas release mode, and a gas sensor for analyzing the gas that was not selectively captured by the trap. The trap may be heated to a first temperature that enables the gas to be adsorbed by the trap, and the trap may be heated to a second temperature that enables the gas to be desorbed by the trap. The gas analysis system may further include a gas flow diverter for directing gas flow past the trap. The captured or released gases may be interfering matrix gases. A method and analyzer for analyzing dissolved gas in an electrical insulating fluid are also disclosed.

Abstract: A method for determining position of a tire pressure monitor equipped on a tire of a vehicle. The method is performed by a controller and comprises: detecting a radial acceleration and a tangential acceleration of the tire; computing a radial-versus-gravity value and a tangent-versus-gravity value based on the radial acceleration, the tangential acceleration and a gravity acceleration; determining an operating state according to variations of the radial-versus-gravity value and the tangent-versus-gravity value; determining whether the operating state is changed to another operating state; and when the operating state is changed, determining a position of the tire pressure monitor according to a change sequence of the operating states.

Abstract: A transmission includes sensors positioned adjacent respective pairs of magnetized bands on a shaft of the transmission for detecting magnetic flux emanating from the bands in response to torque on the shaft. The transmission further includes an electronics interface assembly configured to respectively provide drive signals to the sensors and to receive from the sensors, in response to the drive signals, output signals indicative of the torque on the shaft as detected by the sensors.

Abstract: The present invention provides a DBD lamp used in fluid treatment systems, where the irradiated fluid is used as a low voltage outer electrode instead of a metallic wire mesh. This fluid is in direct contact with the lamp envelope which acts as a two-fold advantage. First, the fluid acts as a strong built-in cooling source. This allows the lamp to be driven at high voltage without forced cooling. Second, the replacement of the wire mesh as the outer electrode by fluid as well as the sleeve eliminates the absorption of radiation from the outer surface of the DBD-driven light source which more than doubles the efficiency of the DBD-driven light source. The inner high voltage electrode remains in the center of the coaxial tube assembly and provides high voltage across the gas to generate excimer formation.
